. b v v FRANK H. CHAPMAN AND OWEN E. KENNEY, OF.TOLE'.DO, OHIO,ASSIGNORS TO THE YOST- ELECTRIC MANUFACTURING COMPANY, OF TOLEDO, OHIO,A CORPORATION To all whom it may concern:

Be it known that we, FRANK H. CHAPMAN and -O WEN E. KENNEY, citizens ofthe United States, and residents of Toledo, in

the county of Lucas and State of Ohio, have invented a. certain new anduseful Pull- Chain Guide for Electrical Sockets; and we do herebydeclare the following to be a full,

clear, and exact description of the invensockets and particularly to thepull chain I guides therefor.

The object of our invention is theprovision of improved means forattachingchain guides to pull sockets, whereby such guides can besecured to or removed from' the socket parts in a-simple', easy, andquick manner, thus. enhancing the practicability and commercial value ofdevices of this character.

The invention is fully described in the following. specification andwhile .in its broader aspect it is capable of embodiment in numerousforms a preferred and a slightly modifiedform' of the invention areillustrated in the accompanying drawings in-which,

Figure 1 isa side elevation of a socket embodying the invention. Fig. 2is a similar enlarged view thereof with parts broken away. Fig. 3 is anenlarged side elevation of the switch-containing insulating-body of thesocket. Fig. 4 is a perspective view of the chain guide embodying theinvention, and Fig.5 is a similar view of a slightly modified form ofthe chain guide.

Referring to the drawings, 1 and 2 designate the base and cap members ofthe shell of an electrical socket, which may be separably securedtogether'dn any suitable or convenientmanner, as is understood in theart,

and ,3 and 4 designate the base and .cap'

members, respectively of the customary in- Specification of LettersZPatent.

PULL-CHAIN GUIDE FOR ELECTRICAL SOCKETS.

terior insulating body of the socket. The insulating members 3 and 4cooperate to .form an interior chamber 5 in which a switch of the pullchain type is disposed,

and are separably secured together in any suitable manner. The meansillustrated for separately connecting the members 3 and 4 comprises twosets of interengaging spring contact fingers 6, with one finger of eachset secured to and projecting, from the base 3 and with the otherfingers secured to and projecting from the cap 4:.

4 The pull chain 7 for the switch attaches in the present instance tothe movable member 8 of the switch, which member registers with orprojects into an opening 9 into the side wall of theswitch chamber 5,which opening preferably extends out on one-side of the inner end of theinsulated member 3.

10 designates an insulating lining that is disposed between the shellbase and the insulating body 3, 4, as is customary in sockets of thistype. The shellbase 1 and insulating lining 10 are provided outwardlyfrom the r inner ends with reglstermg slots or openings, as shown at 11,said openings being capable of registering with the opening 9 in theinsulating member 3. I

The chain guide 12 is preferably of tubular form with its outer endoutwardly flared, and is adapted to project through the openings 11 inthe shell member 1 and insulating lining 10. The inner end of the guide12 is provided with a laterally extending flange or, enlargement 13,which is intended to rest against the side of the insulating member 3'at the margin of the opening .9. The edge of the flange or enlargement13, which is disposed adjacent to the inner end of the insulating member3, is provided with a tongue 14, which projects outwardly therefromlengthwise of the chain-guide and is intended to project between theadjacent'edges of the insulating base and cap members3, 4 within arecess 15 provided therefor, in the present instance, in the edge of themember 3, as shown in Figs. 2.and 3. The recess 15 in. which the tongue14 seats is approximately equal in depth to the thickness-of the tongueso that the insulating members 3 and 4:, when secured together, haveholding or clamping engagement with the tongue. The recess 15 is alsosubstantially equal in width to the width of the tongue 14 so that theside Walls of the recess co-act with the side edges of the tongue toprevent transverse shifting movements of the tongue and chain guide withrespect to the insulating body. v

It is preferable to transversely angle the free end portion of thetongue let, as shown at 16 in Figs. 2 and 4, so that the tongue may havehooked retaining engagement with the interior of the insulating body, asindicated in Fig. 2, thus preventing a with drawal of the tongue frombetween the insulating members 3, 41. until such members have beenseparated from their assembled positions. It will be understood,however, that the lip 16 at the end of the tongue 14 may be eliminatedif desired, as shown in Fig. 5, as the chain guide is prevented frombeing outward withdrawn from the insulating body 1 the shell when theinsulating body is disp -d therein It is evident, that we have providedsimple means for easily and quickly attaching the chain-guide to anelectrical socl'ret without the use of screws or other securing meansapart from the members of the insulation switch carrying body 3, i.

W e wish it understood that our invention is not limited to any specificconstruction arrangement or form of the parts, as it is capable ofnumerous modifications Without departing from the spirit of the claims.

Having thus described our invention what we claim is new and desire tosecure by Letters Patent 1. In an electrical socket, insulating bodyhaving separable base and cap pen tions provided with. a recess betweenthe adjacent edges thereof, and a chain guide having an enlargement atits inner end for resting flat against the outer side of saidbody-adjacent to the outer end of recess, and said eniargeinent having atongue projecting at a right angle therefrom transversely of theinsulating body and fitting" in said recess, said tongue cooperatingwith the walls of said recess to prevent all except endwise movements ofthe tongue when the body parts are in assembled relation.

'2.
